Goblin-made armour was a term used to describe armour made by goblins, generally out of goblin's silver or a similarly enchanted substance, though the term could also be applied to weaponry such as Sword of Gryffindor. Armour made by goblins was unique from that of wizard or Muggle construction in that it would repel unwanted substances such as dirt, and thus never need cleaning, and imbibe any such substance that could strengthen it.
